Patent number: 7961476Abstract: This invention is directed to a support plate for reinforcing a portion of a circuit board. The support plate may be coupled to a portion of the circuit board that is subject to forces (e.g., portions of the circuit board having switches) to prevent flexing of the board. The support plate may be coupled to the circuit board. This invention is also directed to a switch constructed from a button, a label plate, and a backer plate. The label plate and the backer plate may include apertures operative to receive a protrusion extending from the button, where the protrusion is welded to the backer plate. Labels may be printed or attached to the bottom surface of the label plate to protect the labels. In some embodiments, the protrusion may be welded to the backer plate. The protrusion may be operative to engage an electrical switch of an electronic device in which the switch is placed.Type: GrantFiled: February 22, 2010Date of Patent: June 14, 2011Assignee: Apple Inc.Inventors: Stephen Brian Lynch, Dinesh Mathew

Patent number: 7764493Abstract: An electronic device can be provided with a heat-generating component and a cooling module for dissipating heat. In some embodiments, the cooling component may include a fan configured to produce an outflow of air, and a divider configured not only to direct a first portion of the outflow between a first surface of the divider and the heat-generating component, but also to direct a second portion of the outflow along a second surface of the divider. In other embodiments, the cooling component may include a divider and a pressure clip. A first portion of the pressure clip may be configured to exert a pressure on a first surface of the divider such that the pressure may hold a portion of a second surface of the divider in contact with the heat-generating component.Type: GrantFiled: September 25, 2008Date of Patent: July 27, 2010Assignee: Apple Inc.Inventors: Ihab A.

Publication number: 20100091451Abstract: A portable computer is provided that has a housing. A removable battery may provide power to the portable computer. A connector on the battery may mate with a corresponding battery connector in the portable computer housing. The battery connector may be mounted in the portable computer housing using a floating arrangement. This allows the position of the connector to move slightly to accommodate variations in the position of the battery. A cable may be used to route power between the battery and a main logic board. A cover may be used to hold the battery connector and cable to the housing of the portable computer without excessively impeding movement of the connector.Type: ApplicationFiled: December 19, 2008Publication date: April 15, 2010Inventors: Keith J.

Publication number: 20100090847Abstract: A portable computer may include battery indicator light structures. Battery status information in the portable computer may be presented to a user using an array of light-emitting diodes or other light emitters. Light-emitting diodes may be mounted on a printed circuit board. A stiffener may provide the printed circuit board with rigidity. The printed circuit board may include a connector that allows the board to be connected to a main logic board. A switch on the printed circuit board may be actuated by a power button on the portable computer. An opaque member with an array of holes may be used to reduce light bleed between adjacent light-emitting diodes. Diffusing plastic may be mounted within the array of holes. Bumps in the diffusing plastic may mate with corresponding holes on a portable computer housing.Type: ApplicationFiled: December 19, 2008Publication date: April 15, 2010Inventors: Keith J. Hendren, Bartley K. Andre, Duncan R. Kerr, Christopher Stringer, Daniel J. Coster, Chris Ligtenberg, John Brock, Tom Wilson, Dinesh Mathew, Brett W. Degner, Tomas E. Ponce

Patent number: 7697283Abstract: Wall portions, such as wall portions of electronic device housing components, are provided with one or more foot assemblies. A foot assembly can be formed by creating an internal cavity in an internal surface of the wall portion, an external cavity in an external surface of the wall portion, and a hollow passageway extending through the wall portion and between the cavities. The foot assembly can be completed by inserting a foot at least partially through the external cavity and hollow passageway and into the internal cavity, such that an external portion of the foot is at least partially contained within and contacting the surfaces of the external cavity, and such that an internal portion of the foot is at least partially contained within the internal cavity. A portion of the foot may be deformable to at least partially conform to the surfaces defining the internal cavity.Type: GrantFiled: September 29, 2008Date of Patent: April 13, 2010Assignee: Apple Inc.Inventors: Dinesh Mathew, Brett William Degner, Thomas W.

Publication number: 20090173533Abstract: A multi-layered cable consisting of three or more conductive layers separated by layers of dielectric and/or adhesive material. The bottom layer and the top layer may act as return path for the transmitted signals and as a shield to prevent interference between these and external electrical signals. Located between the bottom layer and the top layer, the middle layer may transmit desired signals through the flexible cable. The material selection and specifics of each of the layers should be selected so as to achieve a balance in which the desired electrical impedance and mechanical flexibility requirements are met. The cable may also include one or more vias connecting the bottom layer to the top layer, providing shielding all the way around the flex cable. An additional conductive sock may be used to improve shielding effectiveness of the top and bottom layer and to connect to I/O connector shells and the system Faraday cage.Type: ApplicationFiled: August 29, 2008Publication date: July 9, 2009Applicant: Apple Inc.Inventors: John Brock, Brett William Degner, Dinesh Mathew, Thomas W.

Publication number: 20090174678Abstract: A touchpad assembly for use in an electronic device is provided. The touchpad assembly may include a touchpad frame operative to be placed within an opening in an electronic device frame. The touchpad assembly may include a support plate for supporting a touchpad, and a bracket for receiving a pick button. The support plate and bracket may be manufactured into a same component to increase the rigidity of the touchpad assembly. The pick button may include a varying height to prevent the pick button from deflecting and to make the pick button travel for providing a selection instruction uniform. The pick button may be coupled to the frame using any suitable approach, including using springs connected the ends of the pick button to the frame. The frame may also include pads to muffle the sound of the pick button when it returns to its initial position after having been pressed.Type: ApplicationFiled: September 29, 2008Publication date: July 9, 2009Applicant: Apple Inc.Inventors: Dinesh Mathew, Chris Ligtenberg, Brett William Degner, Thomas W.
